Comparative Dispersal of<i>Trichogramma evanescens</i>and<i>Trichogramma pretiosum</i>(Hymenoptera: Trichogrammatidae) in Relation to Environmental Conditions
Bibliographic record
Abstract
Insect parasitoids have to disperse to locate host habitat and host, and individuals of small species, such as egg parasitoids, are expected to be very sensitive to climatic conditions during dispersal. The effect of 16 environmental variables on the spatio-temporal pattern of dispersion of Trichogramma evanescens Westwood, originating from Egypt, and Trichogramma pretiosum Riley, originating from Quebec, was quantified. In T. evanescens, the accumulation of solar radiation at temperatures >15°C had a significant effect on its dispersion. When >15,000 kJ/m2 were accumulated, more parasitism was observed in a larger area. When wind blew above 15 km/h for >4 h in a day, dispersion also decreased significantly. In T. pretiosum, accumulated solar radiation had no significant effect, whereas it took 8 h of wind >15 km/h to significantly reduce dispersion. T. evanescens, a warm climate species, thus appears to be more sensitive to temperature. Its relatively higher sensitivity to wind condition may indicate that this species is adapted to aggregated or rare hosts, which require more flight control for location.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
